Optimize logistic processes with ABB’s performance manual motor starter MS165

The compact MS165 masters higher currents to provide full control and protection for increased uptime of many applications



Hannover, April 13, 2015. ABB is launching its MS165 manual motor starter, expanding its well-established motor starter family for motor protection up to 30 kW (400 V), 65 A, with inclusive thermal and electromagnetic protection.

“With this new performance product, we complete our manual motor starter family from 10 – 65 A with a wide range of features and a harmonized accessory range,” says Stefan Rößler, Head of Product Management Control and Protection. “The common accessory range helps reduce inventory levels and optimize logistic processes.”

Auxiliary contacts, signaling contacts, undervoltage releases and shunt trips are harmonized throughout the MS116, MS132, MO132 and MS165 family. Harmonized accessories reduce stock keeping units and increase flexibility to optimize ABB’s customers’ logistics processes. Furthermore three-phase bus bars, power in-feed blocks and locking devices for protection against unauthorized changes are available for all types.

The product supports continuous operation within a plant.  In the event of tripping due to short-circuit, the MS165 provides an easy visible fault-indication in a separate window. The integrated thermal and magnetic trip differentiation reduces troubleshooting and downtime of the application thus ensuring a continuous operation. Built-in disconnect function, temperature compensation, trip-free mechanism and a rotary handle with a clear switch position indication also help to reduce downtime of installation. MS165 is suitable for three- and single-phase applications. The lockable handle protects against unauthorized changes.

Improve installation efficiency

Connecting links ensure an easy, fast and secure built-up of starter combinations, such as direct-on-line starters. Additional accessories like the IP 20 terminal shrouds, protection covers for busbars can also be easily mounted.

Panel space is significantly reduced, with a width of 55 mm only, the MS165 range is compact and allows efficient panel sizing while offering a broad scope of particular features.

Manual motor starters are used in applications such as small machine tools, compressors, pumps, saw mills and conveyor systems. Typical segments are HVAC, food & beverage, water and waste water, general machinery critical power as well as building and infrastructure. Manual motor starters are electromechanical protection devices for the main circuit. They are used mainly to switch motors manually ON/OFF and to provide fuse less protection against short-circuit, overload and phase failures. Fuse less protection saves costs, space and ensures a quick reaction under short-circuit condition by switching off the motor within milliseconds. Starter combinations are setup together with contactors.

The MO165 manual motor starter magnetic only is the preferred option for special application that require the division of thermal and magnetic tripping.
